A dozen men were arrested by Willoughby Police on Thursday and Friday nights as part of a prostitution sting. Willoughby Police detectives put an advertisement on a website often used by prostitutes and offered adult services for a special rate of $100 for a half hour with a 20-year-old female, Willoughby Police said in a release.

Twelve men responded to the ad and were arrested without incident after they entered a motel room. Police are not identifying which Willoughby motel was used as future sting operations may occur.

Police identified the arrested men, including age and city of residence, as:

* Timothy D. Asberry, 54, Willoughby Hills

* Bert M. Brown, 55, Beachwood

* Ramone A. Davis, 26, Cleveland

* Gill S. Gurinder, 31, North Royalton

* Nagi J. Haddad, 55, Rocky River

* Bryan Hess, 51, Cuyahoga Falls

* Raymond T. Kern, 50, Mentor

* Eugene Preston, 38, Beachwood

* Johannes Reinhard, 64, Palm Beach

* Efren Romero, 41, Painesville

* Richard M. Salajcik, 47, Eastlake

* Ryan B. Tyna, 42, Hudson

Tyna, a social studies and history teacher at North High School, was placed on administrative leave on Monday afternoon, said Willoughby-Eastlake Superintendent Steve Thompson.

Thompson said he could not confirm why Tyna was placed on leave, but he did say it was related to an investigation outside of the district.

Tyna was also relieved of his duties as the Cuyahoga Valley Christian Academy girls’ basketball coach Monday, Feb. 25, according to a school official.

Tyna had just concluded his second season as head coach of CVCA’s girls basketball squad, said Jason Spodnik, the school’s vice president.

“[On] Monday morning, Ryan [Tyna] … was relieved of his duties once the allegations were confirmed,” said Spodnik. “And they were confirmed via conversation with Mr. Tyna. We have clear standards and expectations of our coaches and their responsibilities as role models.”

Each suspect was charged with soliciting and criminal tools, both misdemeanors. Each suspect also posted bond of $404.

The dozen men are set to return to Willoughby Municipal Court on March 7.
